The existence of cellulose nanocrystals and cellulose nanofibrils has been known for several decades, yet recent advances in science, particularly in the field of nanotechnology, have revealed that these materials contain unique physical properties, particularly high strength properties. Researchers have been studying how these materials can improve paper properties and will present their latest finding this June 24-27, 2013, in Stockholm, Sweden, at TAPPI's 8th Annual International Conference on Nanotechnology for Renewable Materials at the KTH Royal Institute of Stockholm.

The program for this year's event has been released, and one session will focus on using cellulose nanofibers for improving retention and increasing strength in paper. Researchers from Aalto University in Finland will report on improved flocculation of both precipitated calcium carbonate (PCC) and kaolin with the addition of certain cellulose nanomaterials. Researchers from Papiertechnische Stiftung (PTS) in Heidenau, Germany, will report on the importance of adding fillers, celluloses, and compounding agents in the right order to achieve the best results. Researchers from VTT in Finland will report on ways to increase the strength of paper by using filler particles coated with nanoscale calcium silicate hydrate (CS) structures. 

New reports at the conference will present some exciting advances for both within the pulp and paper industry and beyond. The technical program features cellulose nanomaterials in a variety of applications, including:

• Unique and Thin-Film Composites
• Filler and Coating Applications for Different Paper Grades
• Improved Barrier Properties for Packaging Applications
• Cellulose Nanomaterials as Films and Carriers in Medical Applications
• Nanopaper and Iridescent Colored Cellulose Films.
